There are presently a large number of online projects, organisations, committees, and informal entities within the Wikimedia movement. These have mainly developed organically, and there has never been an overall plan.
Often, the relationships between different parts of the movement are unclear. There is no clear venue for holding a discussion between different elements of the movement, and no established method of deciding the outcome of such a conversation. The Wikimedia Foundation has sometimes played the role of driving discussion and decisions on these kinds of issues, but cannot or will not do so consistently.
While there are many positive examples of mutual support and collaborative problem-solving, this lack of clarity poses challenges. Expectations are often unclear and communication is felt to be lacking. Tasks and projects, including some of strategic significance, do not happen because it is presently no-one's job to do them.
